A battery pack for electrically coupling with and securing to a portable electronic device having a device connector and one or more user interface components includes an electronics section and a latch section. The electronics section includes a battery compartment configured to hold one or more batteries and a connector mechanism configured to interconnect with and form a waterproof seal around the device connector. The latch section is pivotably coupled to the base portion and configured to pivot relative to the base portion to transition the battery pack between open and closed states. In the open state, the electronics section and the latch section form an open frame structure configured to enable installation of the portable electronic device in the battery pack. In the closed state, the electronics section and the latch section form a closed frame structure configured to secure the portable electronic device within an opening defined by the closed frame structure.

A textile interconnection system for a textile substrate. The textile substrate may include at least one conductive fibre configured to transmit at least one of a power or data signal. The textile interconnection system includes a textile receptacle projecting from the textile substrate to define a cavity for receiving a controller device. The textile interconnection system includes a textile docking device received within the textile receptacle and coupled to the at least one conductive fibre of the textile substrate to electrically interconnect the received controller device and the textile substrate. The textile interconnection system includes a housing coupled to the textile docking device and received within the textile receptacle to mechanically interconnect the received controller device and the textile substrate.
